The Mahdiyya Movement in Sudan was primarily a response to **Egyptian and Ottoman control**.

This movement emerged in the late 19th century as a reaction against the political domination and social strain imposed by the Egyptian rulers who were under the influence and authority of the Ottoman Empire. The local Sudanese population experienced heavy taxation and social injustice under this regime, and there was a sense of nationalistic and religious fervor to liberate Sudan from foreign rule.

The leader of this movement, Muhammad Ahmad, proclaimed himself the Mahdi, or the "Guided One," believed to be an Islamic messianic figure. His declaration and guidance were rooted in the belief that he would restore justice, reform Islam, and remove foreign imperialism and corrupt local practices.

Thus, the Mahdiyya Movement was fundamentally driven by **the desire to overthrow the existing control of Egypt and the Ottoman Empire**, intending to establish a self-governed state based on Islamic principles and Sudanese national identity.
